Employment

since 2022 assistant at the Institute of Phonetics, Faculty of Arts, Charles University

Research Interests

I am interested mainly in the variability of the speech signal depending on a speaker’s individuality and in the possibilities of speaker identification in the forensic domain. This topic was also the focus of my dissertation project.
